I thought this book was funny because the science teacher's name is silly. My favorite part in this book was when Captain Underpants and Professor P. Poopy Pants were fighting becuase there is a flip book of them fighting. This book is a part of a series of Captain Underpants. It is book four. This one is different from the others because it has a list of funny names you can name people but not to hurt their feelings. Other Captain Underpants' books do not have that.
I recommend this book to people who like funny books. If you like flip books and funny stuff, you would like this book. My favorite part is the flip book. Maybe other parts will interest you.
